Week 8 first draft Confirmation

Week 8 first draft Confirmation

1. What is my thesis?
The lie detector is not accurate to use in the court as the evidence.

2. What types of source am I using to defend my thesis? 
I am using expert opinions of  the thesis and articles.


3. Are my arguments mostly based on evidence, logic or emotion?
My arguments are mostly based on evidence and the fact. So I think this point make my argument clear. Also have a little emotional appeal in the last part.

My Confirmation

According to my research, there are 3 limits for lie detector. 

First, FMRI of cognitive subtration is just relative. Most of the people think the vitalized part of the brain have connection with the lie in the result of the FMRI. However, according to the study, there are some part that are vitalized in FMRI but have no relative with lie. So, it means there are some vitalized part that are not related with the lie. The part of the brain can be vitalized to just keep the balance in the brain or other reasons. We can't know exactly why the part is vitalized. So the FMRI of cognitive subtration is just relative and not accurate.

And following two limits are related with both polygraph and the FMRI. 

Second, We can't remember all the thing exactly. There can be false memory. And why the false memory form? According to my research, if the social demands on individuals, people remember that pressure. And individuals can be encouraged not to think about whether their memories are real or not. It means people cannot realize true memory and false memory themselves. Even there is no accuracy that the true memory is really true. 

Lastly, the way to measure lie(both of polygraph and the FMRI) is easy to interrupt from environment. The recent study found that interruption movement like moving the finger is let the credibility decrease about 33 percent. So the result of the lie detector is not accurate. Because the result can change as where to test, when the experimenter test, or even how the experimenter feels at that time. 

 I also find the information about change the standard to accept evidence in the court. In 1923, there was a boy named 'Frye' who  was prosecuted with the robbery and murder. In his trial, the court rejected the evidence from the lie detector because the lack of the general acceptance. This precedent called 'Frye Rule' after this trial. And over the 50 years, this rule performed the standard of the acceptance the evidence. However, after the making the principle of the Dovert in 1993, the lie detector's result started to accept in the court as the evidence. And nowadays the frequency of acceptance the result of lie detector increase. According to the statistics, from the making the principle in the 1993 to 2003, 19 states in the United States of America accept the evidence in the court. I think this tendency is not proper. And these three limits and one precedent can support my argument, that the result from the lie detector cannot be used in the court as the evidence.
